How to read the shelf life chart
Counter, fridge, freezer and after opening: what each column of the Shelf Life Charts means, the two-hour rule, and the foods that surprise people.
The Shelf Life Charts in Kitchen Tools & Recipes answer one question: how long will this keep? There are four tabs, Meats & Seafood, Fruits & Vegetables, Dairy and Breads & Pastries, and every row has the same columns. Here is how to read them.
The columns
- Counter/pantry is room temperature. For anything perishable it says 2 hours, and it means it.
- Refrigerator is how long it keeps in the fridge. Where opening makes a difference, the row says so.
- Freezer is how long it stays good frozen. The frozen vegetables row puts it plainly: food kept at 0°F / -18°C stays safe indefinitely, and the time is about texture, not safety. That holds for the other freezer times too.
- After opening is the clock that starts when the packet is opened. It is often far shorter than the date on the pack.
- Notes give the reason, where there is one worth knowing.
Opening the packet changes everything
A few rows from the chart show how much:
| Food | Counter | Fridge | Freezer | After opening |
|---|---|---|---|---|
| Deli meat | 2 hours | 2 weeks unopened | 1 - 2 months | 3 - 5 days |
| Eggs, liquid in a carton | 2 hours | 1 week unopened | 1 year | 3 days |
| Canned fish or meat | 2 - 5 years unopened | 3 - 4 days opened | Not in the tin | 3 - 4 days |
| Cheese, shredded | 4 hours | 1 month unopened | 6 - 8 months | 5 - 7 days |
| Milk | 2 hours | 1 week | 3 months | 5 - 7 days |
| Butter | 1 - 2 days | 1 - 3 months | 6 - 9 months | 2 weeks for best flavour |
Deli meat is worth a second look: it is one of the few foods listeria grows on in the fridge, so the 3 to 5 days after opening matter more than the date on the pack. Canned fish keeps for years in the tin and for days once it is open, and the chart’s advice is to move it out of the tin as soon as you open it.
The two-hour rule
Most perishable rows say 2 hours on the counter. That is the limit for perishable food left out at room temperature, and the rotisserie chicken row adds the detail people miss: the two-hour clock starts when the chicken leaves the heat lamp, not when you get home.
Marinating raw meat is the one row that says never on the counter: marinate it in the fridge for 1 to 2 days, or freeze it in the marinade. If you want to serve a used marinade as a sauce, boil it for a full minute first.
Things that surprise people
The notes column is where the chart earns its keep. A few of them:
- Potatoes, sweet potatoes, onions and garlic stay out of the fridge. Cold turns potato starch to sugar, and they brown wrong. Keep onions and garlic cool, dark and dry, and never next to the potatoes.
- The fridge kills a tomato’s flavour. Keep tomatoes on the counter, stem down, out of the sun.
- The fridge stales bread faster than the counter does. A fresh loaf keeps best cut side down on a board. Sourdough outlasts yeasted bread, because its acidity is a preservative.
- Mould on hard cheese can be cut off, with an inch to spare. On soft cheese, throw it out: the mould goes right through.
- Wash berries and grapes only just before eating. Water speeds up the mould.
- Oily fish keeps less than half as long frozen as lean fish, 2 to 3 months against 6 to 8, because the oil goes rancid long before the fish is unsafe. Bacon is the same story: one month in the freezer, because the salt turns the fat rancid.
- Ghee keeps for months at room temperature. The milk solids are what spoil in butter, and ghee has had them taken out.
- The fridge door is the warmest shelf. Keep milk on a middle one.
- A cheesecake is a custard in a tin and belongs in the fridge. So does pumpkin pie, which counts as custard.
When the chart and your instinct disagree
The chart is guidance, not a food-safety authority. How long food really keeps depends on how fresh it was when you bought it and how cold your fridge actually is. Follow your local food-safety guidance, and if you are not sure about something, throw it out.
Where to find it
Open Charts and choose Shelf life at the bottom, then pick a tab at the top. The first column stays put while you scroll across. In version 3.3 you can tap the pin to put a tab on the app icon’s press-and-hold menu, or add a Shelf Life Charts widget to the Home Screen.
